Application filed May 27,1825. SeriaI No. 33,077.

My invention relates in general to driving mechanisms for; reciprocating or oscillating machines of the type in which, for instance, a cylinder is rotated first in one 11 direction, and then in another direction, it being desired that the revolutions in one direction shall be as nearly as possible equal to the revolutions. in the opposite direction.

Although myinvention may be applied in connection with planers, shapers and kindred machines, its especial application is to rotary cylinder washing machines,

and it is in order to control the oscillation of these cylinders that my invention comr prehends. the special'contrivances, and the construction, arrangement and combination of parts, herein illustrated and described.

My novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claim.

For the purpose of illustrating my invention, I have shown in the accompanying drawinga typical embodiment of it which in practice-Will give reliable and satisfactory results. 7

It is, however,- tobe understood that this embodiment is typical only and that the variousinstrumentalities whichmy invention comprehends can be variously arranged and organized, and that the invention is not,

therefore, limited to the precise arrange ment and organizationof these instrumentalities as herein set forth.

In'the drawings :f I Figure 1 is a top plan view of a machine embodyingmy invention-.-

Figure 2 is a longitudinal elevation viewed-from the rear or lower side of the machine as illustrated inFigure 1.

Figure 3 is a transverse section on the line 3--3' of Figure 2.

Figure 1 is-an' end elevation viewed from the left hand end of Figure 1;and c Figure 5 is an enlarged, sectional detail on the line 5-5 of Figure 1.

Similar numerals of referencev indicate corresponding parts.

Referring to the drawings V 1 designates a frame work of any preferred character. 2 is a motor mechanism or prime mover of any preferred character, such, for instance, as an electric motor or a single belt pulley, the driving shaft of which driven.

is connected through a motor shaft pinion 3 with a driven gear wheel 4; on a driven or clutch shaft 5'mounted in bearings 6 erected from the frame Work and continuously r0- tatmg 1n one (11190131011, Y I

7 1s a' driving gear wheel first on the clutch shaft 5, which meshes with a drivengear wheel. 8 fast'on a connecting or pinion shaft 9 suitably housed in the frame work, and 1n the mounting of the parts lying in mounting of the gear wheel 7, and in mesh with a gear wheel 11 mounted upon a supplemental or driven shaft 13, through a pinion 13? on the, outer end of which the washer or element to be v reciprocated is The gear wheel 10, is, as stated, in mesh with a gear wheel 11 on said supplemental shaft 13, in turn in mesh with another gear wheel 12 on the connecting shaft 9, so that, as is obvious, the gears and 11 drive the supplemental shaft 13in one direction, and

in the opposite direction.

The supplemental shaft 13,-as above mentioned, is'a driven shaft for the'purpo'se of effecting the reversing rotation of the washingcylinder or otherrdriven elementwhich is to be alternately moved first in one'direction and then in the opposite direction. a

Intermediate-of the gear w reels '7 and 10, there is mounted upon the clutch shaft a clutch unitcomposed of clutch elements 1-5.- and 1e; both-fast upon the clutch shaft, respectively connectible' with gear wheels? and 10', and both adapted to be alternately thrown into operation by a sliding clutch sleeve 14*; the clutch unit as'an entirety embodying, for instance, such a well-known construction as is set forth in U. S. Letters Patent No. 1,011,355, issued December 12th, 1911, and in U; S. Letters Patent No. 1,235,- 561, issued August 7th, 1917; which being well known to those skilled in the art requires no detail of description herein.

A clutch unit of the foregoing construction is an article of commerce and I prefer to employ it, although, as is obvious, other clutch constructions maybe mounted upon the clutch shaft, it being only essential that the gears 7, 8, 12 and 11 drivethe shaft 13 ill?) it be double clutch unit so mounted upon the clutch shaft 5, as through the medium of a sliding or longitudinally-reciprocable clutch sleeve 1%- to be adapted to be shifted end-wise in either cirection upon said clutch shaft 5, to effect the alternate operation of the clutch elements 1% and let, and the gear wheels 7 and 10.

For the purpose of putting into operation a clutch unit of the character illustrated I resort to the following construction 15 is a worm on the clutch shaft 5, which is in mesh with a horizontally disposed worm wheel 16 on a pivot shaft 18 mounted in the framework.

The upper face of the worm wheel 16 is formed with a cam groove 17, see Figure 5, in which travels an off-centre roller pin 20 extending downward from the under surface of a horizontal or cross plate 19, fixedly connected with a longitudinally-extending operating rod 21 housed in bearings 21* in the frame and adapted to be longitudinally reciprocated by the travel of the roller pin :20 within the cam-way 17.

Parallelin the operating rod 21 is a fixed guide rod 20 directly supporting the bearings 21* in the framework.

22 is a recessed or channeled shifter arm extending inwardly from and right angularly to the operating rod 21 to which it is fixed. This shifter arm is adapted to receive the clutch arm 23 within its preferably upturned divided inner end.

This shifter arm serves to occasion the longitudinal reciproeatory movement of a clutch arm 23 extending radially from the clutch sleeve 1% and connected therewith.

24 is an operating handle pivoted at 28 within a slot or channel 26 formed in the outer end of the clutch arm :28 and so formed as to embody a stop 27 against which the operating handle rests and is self-supported when the clutch arm is thrown into its inner or non-operative position or that represented in dotted lines in Figure l.

When the clutch arm is in its forward or operative position its handle rests and slides upon a check rod 01" stop 25, as shown in Figure 4. This stop is supported in any convenient manner which, for clearness, is not illustrated.

I prefer to form the clutch arm with a weighted head 23*.

The operation of my mechanism so far as it may be useful further to describe it, is as follows The reciprocatory clutch sleeve 1r, as c:; plained, is locked and operative according to its temporarily locked position, with either the right hand member let or the left hand member 14: of the clutch unit.

The reciprocation of the clutch sleeve let after the clutch arm 23, has been thrown into engagement with the shifter arm as shown in full lines in Figures 1 and t, occasioned by the reciprocation of said shifter arm 22, due, as explained, to the reciprocation of the operating rod 21 under the throw of said rod through the reciprocation of the plate 19 occasioned by the travel of the roller pin 20 in the cam groove 17 in the worm wheel 16, which latter is constantly in operation through the worm 15 on the constantly rotating clutch shaft 5.

In the neutral position of the parts and when the mechanism is at rest, the clutch arm 23 is thrown over into its rear position as illustrated in dotted lines in Figure l.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

A driving and reversing mechanism comprising a motive mechanism, a clutch shaft, clutch elements upon said shaft, a shifting and oscillatory clutch sleeve having a radial arm also upon said clutch shaft, gearing connective of the motor and the clutch shaft to rotate said shaft constantly in one direction, a supplemental driven shaft, gearing connective of the clutch shaft and the supplemental shaft to rotate said supplemental shaft alternately in opposite directions, with which are combined a means to shift the clutch sleeve comprising an operating rod having a shifter arm mounted upon it and adapted to engage a clutch arm extending radially from the clutch sleeve, and means comprising a worm wheel having a cam-way in its face, and a cross plate having a roller travelling in the cam-way of the worm wheel and connected with the operating rod to continuous- 1y reciprocate said operating rod.

In testimony that I claim the foregoing as my invention, I have hereunto signed my name this 23rd day of May, 1925.
